Horizon Dev LLC

Horizon Dev rebuilds legacy data platforms for established companies stuck on outdated systems. We've completed 100+ production deployments, specializing in modernizing 10-30-year-old platforms without disrupting daily operations.

Our team of 15 engineers works with React, Django, Node.js, Supabase, and PostgreSQL. We handle the full modernization lifecycle: assessment, data migration, API integration, OCR data extraction, custom application development, and ongoing support.

Notable projects include rebuilding VREF Aviation's 30-year-old aircraft valuation platform (67% revenue growth, 4.2x ROI in 18 months) and taking over a Microsoft website serving 1M+ annual users for a 2.0 launch shipped on deadline.

We focus exclusively on mid-market companies with complex data workflows that need their legacy systems rebuilt, not patched. If your platform is 10+ years old and holding back revenue, that's exactly what we fix.
